Specification-forming lpartei' Letters Patent-No. 47,732, dated May,1855 -To all whom-it may concern.-

Be it known `that I, 'GEORGE Arrnnosa, of the city, county, and State ofNew York, have invented 4a new andplxnprovedH-oisting Apparatus; and Ido hereby declare vthat 4the following is a full, clear, and exactdescription thereof, `reference being'had to the accom- .l

panying drawings,`making apart ofthis speciiication, in which v'Figure 1is a front elevation of the .upper end lower portionsot my apparatus.Fig. 2 is a vertical section through Fig. 1. Fig. 3' is a horizontalsection through the elevator or 'hed-rack.

Similar letters of referehceindicate corresponding-parts in the threeligures.

This invention. relates to anew and imfproved apparatus which is adaptedfor elevoting building material from `a lower to an V ripper story of a.building, in. portable recon` taole'sgand which Ais so constructed thatthe laborious part of the operation can `be performed by ,horse or'steam power, as ywill. be hereinafter describedj i i Another ob'ect ofmy invention is to so apply an elevator' o r bod-rack, which isadaptedfor receiving portable receptacles or hods,'to

an elevating apparatus that said rack willbe y automatically caught epdretained in an ele'-V vated position when carried up to its fullestextent, as will be hereinafter described.

To 'enable others skilled in the art to make and use my invention, I'will describe its construction and operation; i y

In the accompan "ing drawings, A- A repre sent two vertical guides,which sustained I in an upright position by means! of -the iloorjoistsand'cross-beams`4 which are` secured' thereto.4 Ifsaid guides are madeotrope they can bestretched tightly in any suitable inanner. i The upperends of the guides Al A are secnredto a frame, B, the horizontalKcentral ybeam of whichrecsives two sheaves, a b, over which pass a ropeor chain, c, one end of which is suitably connected to a hodrack, O,which isnotched to receive the edges of the guides A A, so that these'guides will keep the rack in a 'proper position while it is beingelevated or depressed. The'opposite end of said rope c -is carried downand connected to one of a series of drums, e f g g', which are, allkeyed to a shaft, g2, thathasitsbearings in a frame,

D. ,This franie'should be so constructed that itoan be readily secured,down in place, and removed whenever it is found necessary. A

draft-rope, h, connects with `the smaller drum A e, and is woundaroundit in such manner that when this rope iscarried ott' by means of ahorse or otherwise, `it will rotate the 'series of drums and wind up therope c upon its drum f, thus elevating the hed-rack. It' itis desired tomove ,the bod-rack very rapidlythe horse :moving 4slowly-the rope c iscarried' around the largest drum g.

` The drinn g isintended to lreceive the brakestrap t', to which arope,j; is attached, and by pulling this ropej the brake i can be' drawntightly about. its drum, which will stop the hed-rack either, in itsascent or descent. i By v means of this brake arran gementthe attendantcan 'stop the bod-racket any desired height, orhcanreeuletejts desueiitu`In Fig. 2 l have represented" acunterf'- site each other. These boxescontain spring-f latches m m, which are actuatedby levers a n, and arope, p, as 'shown in Fig. l. These latcheshave their noses or. catchingends so formed as to be thrust back by the projecting ends of the top ofthe bod-rack when the lateV ter is elevated to itsy fullest extent, andthen to spring backnnder said projecting ends, thus catching andsupporting thehod-rack in an elevated position. When the cord p, whichconnects with the two latchlevers mi, is pulled, 'these latches willrelease the bod-rack and allow it to descend. This vertically-slidinghod- `rack or elevating-carriage O is adapted-for receivingandretaining.in place the common portable' hods s s s s, which are nsnally'canriedupon the shoulders of laborers.

i In Figs. 1, 2,- and 3,1 have represented such hods applied tothe rackG' in such manner that theycan be readily removed therefrom for iillin gor emptying. This rack is constructed as follows: t t are two'horizontalledges secured to the-sides of the box C, and notched to receive andsupport one end of a had. Bey in the ledges are of a V shape, and hencepreplied to or readily removed from the hodrack.

i of the hoisting apparatus, raises the elevator lthe required height,when the hods are re- `moved and their contents emptied, after whichtween these two ledges, t t, another ledge, u, which is notched on bothsides to receive the opposite ends ofthe hods. The notches vent the hodsfrom tilting when seated in them, and at the same time allow the hods tobe ap- The operation of the apparatus is as follows: A horse orothcrpower being attached to the draft-rope h, on the smallest pulley e Uwith the required material-say, twice the distance the horse movesforward. The draft rope li being placed aroundthe middle pulley, willraise the elevator as three is to one, or in v.proportion to' therelative diameters of the pulleys. The hodsbeing filled with thematerial to be elevated to an upper story of a building, and placed inthe elevator, asshown in Figs'. l and 2, the latter is then elevated tothe empty hods are again returned to the elevator, and the attendantbelow notified, when `he starts the horse backward and allows theelevator to descend again by 'its own gravity tothe place from' whenceit started..` i

B v means of the brake whichis applied to the drums, the attendant canallow the elevai tor to descend more rapidly than the horse could back,and yet not so fast as to injure or throw out the hods. to stop theascentoi' the elevator at the desired height. i Y

What I claim as new, and by Letters Patent, is-

l. Ahoisting apparatus which employs an elevator, C, adapted forreceiving and holding in place hods or other portable vessels, guide-Ways A A, pulley-rope c, pulleys a, b, .and drumsto f g, together with abrake, all arranged and operating substantially as described.

2. Providing the elevator C with racks which are adapted for receivingand retaining in place portable hods s s, substantially as de'- seribed.

3. Springlatehes m m and levers n n, in combination with the guides A A,and eleva'- tor or hed-rack C, substantially as described.
